WHEEL OR PU LLEY.

SPECIFICATION forming part of Letters Patent No. 322,581, dated July 21, 1885.

Application filed January 22, 1885. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE P. CLARK, of Windsor Looks, in the county of Hartford and State of Connecticut, have invented a certain new Improvement in the Construction of Wheels and Pulleys, of which the following is a full, clear, and exact description.

This invention relates to wheels or pulleys made of paper, leather, rubber, or similar material, or having tires or outer wearing-surfaces made of such material; and my invention consists, principally, in constructing the wheel with side plates and penetrating-points to enter the material composing the body or Wearingsurface of the wheel.

In making the wheel of leather, paper, or similar material, I compress sheets of the material in a vise or under heavy pressure between the side plates, so that the material becomes asolid and nearlya homogeneous mass. Then I turn or otherwise work down the outer edge or wearingsurface of the compressed material to the shape and size required. This method constitutes a feature of my invention; and the invention also consists of the special construction of a wheel having a tire of compressed material held by a ring and side plates, each having penetrating-points,as hereinafter described.

The invention finally consists of the construction, arrangement, and combination of parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a small wheel or pulley made in accordance with my invention, with side plates having penetratingpoints. Fig. 2 is a sectional elevation of the same, taken on the line a: a: of Fig. 1. Fig. 3 is a plan View of the inner face of one form of side plate. Fig. 4 is a side view of a large wheel having a tire or wearing-surface of compressed material. Fig. 5 is a central sectional elevation of the same, taken on line y y of Fig. 4. Fig. 6 is a perspective view of a central plate with penetrating points used in the larger forms of wheel. Fig. 7 is a side elevation of a wheel where separate penetrating and clinching points are used, passed through the side plates. Fig. 8 is a transverse central sectional I elevation of the same. Fig. 9 is a sectional elevation of a wheel where barbed penetrating points are used for holding the side plates. Fig. 10 is a similar view where bolts or rivets are used for holding the side plates; and Fig. 11 is a transverse sectional elevation of a wheel employing plain pegs or penetrating' points driven into the material of the wheel, the side plates being afterward put on.

My new and improved wheel is composed of the body A.,of rubber, paper, leather, or other similar fibrous or compressible material, the metal side plates, B B, the penetratingpoint a, and the central tube, 0. The point a I prefer to make upon the inner surfaces of the plates B and integral with the plates, as shown in Figs. 2, 3,-and 5, and I prefer to make the point a of such length relative to the thickness of the body A, that when forced through the body A theirpoints will be turned and clinched, as shown at a in Figs. 2 and 8, and for causing the points a to clinch properly when the plates are pressed upon the body A in making the wheel I shall in most cases form the plates B with the triangular ribs or flanges 01 upon their inner faces, at the base of the points a, so that the points of the opposite plate after being pressed through the body A will come against one of the inclined surfaces of the ribs d, and thus be deflected and caused to clinch.

In forming the wheel shown in Figs. 1 and 2, I place sheets of leather or paper or pieces of rubber or other material to compose the body A upon a long tube; then I put the plates B upon the same tube and place the whole in a suitable vise and press the plates B toward each other. This will cause the points a to penetrate the material of body A and to pass through said material from each side. The pressure will also compress the material of the body A into a very solid state, and at the same time cause the points a to be clinched against the side plates, B B, so that they hold the material of body A in its solidly-coinpressed condition and hold the plates in place. The long tube above mentioned is then cut off close to the side plates, B B, which forms the axial tube a, and then the wheel is put in a lathe and the outer surface of the bodyA.

turned true and to the required shape accord- D of the casting C, as shown in Fig. 5. In 55 ing to the purpose for which the wheel is-to be used.

Instead of forming the penetrating points anpon the plates B and as a part of them, I may form countersunk opening a through the side plates and employ separate headed nails or points driven into the openings a into the body A, the nails being of such length as to pass through the body A and clinch, as shown in Fig. 8; or instead of using nails to clinch, I may use short barbed nails or penetrating points, as shown in Fig. 9, driven through countersunk openings in the side plates, B, the brads or spurs on the nails or points serving to hold the material composing body A in compressed condition, and also to hold the plates B securely in place.

Instead of using clinching-nails with the side plates, B, having countersunk opening, I may use rivets, as shown in Fig. 10, driven through the plates and body A, and headed at both ends; and in some cases I shall compress the-material composing body A, and secure it by pegs, as shown in Fig. 11, and use plain side plates, B B, afterward applied and held at the sides of the body A by upsetting the ends of the central tube,c, as shown in Fig. 11.

In making large wheels-such, for example, as that shown in Figs. 4; and 5I use a malleable-iron spider or frame, 0, cast with the plain circumferential surface D and circumferential side flange,E, that is the equivalent of one of the side plates B, and employ the separate annular ring B to hold the body or tire A of compressed material.

The penetrating points a may be formed as a part of the flange E and ring B; or the flange and ring may have countersunk openings made in them and separate points driven through the openings into the compressed material A.

The body or tire A is made of sheets of paper, rubber, leather, or other similar material cut in annular form and placed upon the plain circu mferential surface D, and then compressed between the flange E and ring B, the points entering the material composing body or tire A, as illustrated in Fig. 5. The ring B is held in place by the screws f.

WVhen it is desired to make this form of wheel very strong, I shall employ the annular plate F, which is formed upon each side with the penetrating points 9, and adapted to be placed upon the plain circumferential surface forming the wheel with the ring F, one'half of the material composing the tire A will first be placed upon the plain surface D, and compressed wholly or in part against the flange E. Then the ring F will be put in place and forced against the material already on the plain surface; then the remainder of the material to compose the tire A will be put in place on the plain circumferential surface D, and the ring B applied and the whole compressed in a vise, which will cause the penetrating points to enter the material of tire A and the points 9 to be clinched, as shown in Fig. 5. The screws f will then be put in place, which completes the wheel, save the turning or working down of the outer surface of the tire A, which may be done in a suitable lathe.

Wheels constructed in the manner herein described are practical for various purposes, and are cheap and durable.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. As a new article of manufacture, a wheel or pulley composed of a body of paper,leather.

rubber, or other similar material, compressed and held by penetrating points and side plates, substantially as described.

2. A wheel co m posed of the casting 0, formed with plain surface D and flange E, in combination with body or tire A, of compressed material, side plate, B, and penetrating points a, substantially as set forth. I

3. The ring F, formed with penetrating points 9, in combination with casting O, flange E, and plate B, and compressed tire or body A, the flange and plate B being provided with penetrating points, substantially as described.

4. The method herein described of forming wheels of paper, leather, rubber, or other compressible material, which consists in compressing the paper, leather, rubber, or other material between side plates, inserting suitable penetrating points to hold the material in a compressed state and to' hold the side plates, and, finally, in working down or turning the outer surface of the compressed material to v the desired shape, as set forth.
